To ((ZZ'ICILOM- it may concern:

lie it known that IrAnonrr-r WILLIAM lloui. a citizen of the United States, residing at Cleveland. in'the county of Guyahoga and State of Ohio, have invented a certain new and useful Grease-Gap, of which the .lollowing is a specification;

This invention relates to'grease cups harinrj rotatable caps. and has for its object a particularly simple ainl/ellieieiil. construction wherein the rotatalllr rap is held from imintentional turning; and the invention ronsists in the combinations and eonstructionshereinal'ter sol l'orth and claimed in describing this invention. i'el crence is had to the accompanying drawings. in which in all the views.

Figure l is a longitudinal sectional view. part l in elevation, ol' a grease cup embody ing m v invention, the cover being shown as parll out oi its final position. Fig. 2 is a fragmentary sectional view of the upper part of the. grease eup showing the cover as in its tinal position when said parts are completel) assembled.

This grease cup comprises, generally, aba'se having a barrel portion, a cover including inner and outer cap members having perforations therethrough, the inner cap member being secured to the base and the outer cap member being rotatably mounted on the iner cap and he-ingrotatable to bringits perforation into and out of registration with theperforation ol' the inner cap member, means for holding the cap members from separatiom and friction means for holding the outer cap member from unintentional turning.

l designates'the base of the grease cap, which here shown as :lormed with a barrel portion 2, aml a tunnel-shaped part depending from the barrel portion and terminating in a hollow threaded stein or nip ple lb means o l which the base is connected to the part to be lubricated. The base here shown is also formed with a central tube Ii extending-into the stem or nipple. and in which is located a wick (3 b V-mea.ns 01 which the grease. is conveyed from the base to the part to be lubricated.

7 and 8 designate, respectively, the inner and outer cap members forming the cover, said cap members having dome shaped tops 9, 1O engaging each other, and annular side walls 11, 12 spaced apart from each other. The wall 11 of the inner cap member projects beyond the edge of the annular wallof the outer cap member and snugly fits within the upper end of the barrel and the wall -30 112 of the outer cap member loosely fits or laps over the upper end of the arrel Q. The wall 12 is also knurled for facilitating the turning thereof. The tops 9, 10 are formed with perforations 13, it arranged to he brought into and outot alinement during turning o'l the outer cap member 8, in order that grease may be inserted into the rap and the perforations closed after the rap is lilled. The cap members are held from separation by a centrally located pin or ri.vet 15 having inner and outer heads, the pin serving as a pivot about which. tie outer eap member 8 rotates. The friction means lar holding the cap member 8 from unintentional turning is interposed between the anunla r walls of the cap members 7, 8 and between the upper edge of the barrel portion of the base and the top 10 of the outer cap member 8. Said means comprises a spring TO v 16 eneirclingthe wall ll. of the inner cap member and located in the space between the annular walls 11, 12 of the inner and outer cap members. Said spring is a compression spring consisting of a single coil normalh havingits opposit ends 17 dellected in opposite directions, as shown in Fig. 1, the spring being compressed into a plane as the eorer is ass abled onto thebarrel 2, that as the inner cap member 7 is pressed into the barrel .2, as shown in Fig. 2. llence, the ends of" the spring tend to press in opposite directions toward the upper edge of the barrel 2 and the opposing surface oi the top of the outer cap member 8. Said 't rirtion means also usually includes a ring shaped shoe 1R interposed between the spring in and the top of the ontereap member a. The inner cap member is constructed to snugly tit within the barrel 2 so that when the parts are assembled. the cover is permanentlv in position. l n 't'orming the grease. eup. the ea p members 7. R are a'ssei'nbled and the shoe IR and spring; lt' placed around the annular wall ll of the inner cap member and the advance edge of the wall 11 in serted in the upper end of the base 1, as

seen in Fig. 1. The cover is then pressed toward the base to shove the Wali ll of the inner cap member into the base, as seen in Fig. 2.
